I have set sail for a few hours with 4 adults and 2 children. I knew in advance that the primary job of two adults at all times would be to watch conditions and keep the boat from heeling. Actual sail trim would be at a minimum. Two adults charged as vigilant sitters. I am still a novice so it took an inordinate amount of time to review emergency procedures, what was necessary to ensure the boat remained balanced, who would do what under a variety of circumstances, what would happen if behavioral issues surfaced and on and on and on. I would not consider more than people than that, nor any different ratio of adults to kids. A good time was had, though it was not a relaxed sail. If we repeated this a few times, I'm sure we'd be able to do more sailing and less logistics. Doubling that number on a boat with substantially less displacement, smaller cabin and cockpit than mine is unimaginable and not just as a matter of comfort. That means people are forced out along the toe rails to the bow, too many heads to watch on every tack, and needs a skipper who can keep the boat under control even when the balance shifts suddenly and significantly as an overloaded 27 will. Now as a means of population control . . . .
